Only water vapor molecules evaporate (not salt molecules)
it is precipitation
Precipitation provides more water for the oceans and lakes, thus providing more water to be evaporated and turned into clouds.
because huge amounts of water evaporate from the oceans every day. this evaporated water is carried by the wind around the globe. eventually, the water fall as rain or snow. without this precipitation, life on land would not be possible.
The principal source of evaporated water in our atmosphere is also the largest source of water on our planet. It is the water evaporating from our oceans. Water also evaporates from lakes, rivers, streams or any other place where water can be found.
Because rain is evaporated oceans and sea water
The yearly total precipitation over the oceans is greater than over continents because oceans cover more of the Earth's surface and therefore have a larger area from which to receive precipitation. Additionally, the oceans are able to retain heat better than land, leading to more evaporation and subsequent precipitation. Ocean currents also play a role in transporting moisture to different regions, contributing to higher precipitation levels over oceans.
Most water is evaporated from oceans.
Water is evaporated from oceans. It is returned back to oceans.
In the water cycle the water from the oceans are evaporated into clouds by the sun. As more water is evaporated up in the clouds, more water would fall down as precipitation. The water falls because eventually there is so much water in the clouds that the clouds could not hold it all and the rain begins to fall. The precipitation either releases as rain or as snow. The water or rain flows off the runoff and goes bad into the ocean. Plants also use precipitation to keep themselves healthy, decreasing the chances of becoming dead. The water cycle affects water table levels because for example if the water evaporates into the clouds and the precipitation goes into the soil for the plants that will lower the water table levels because the water goes into the plant and can no longer go back into the oceans.

Oceans are kept full by the constant drainage (via rivers, streams, etc.) and precipitation of water into them, causing an equilibrium between what is evaporated and what is coming in. Since Earth is virtually a closed system (no water generally leaves earth or comes to Earth), the amount of water on Earth remains a constant, and whatever is evaporated condenses eventually and precipitates over land or the oceans in the form of rain, snow, hail, etc., and (after melting, if frozen) flows back to the oceans.
Sea level doesn't drop despite oceans experiencing higher evaporation than precipitation because the water that evaporates from the oceans eventually returns as precipitation, maintaining a balance in the water cycle.
No. When water is evaporated into the atmosphere, the salt isn't evaporated with it. The water in the water cycle is always fresh water, and when it drains into the oceans it dimply diludes the ocean from having such a high salt content. The water cycle is always continuous and if it ended, we would all die.
